DANIEL CHAMBERLAIN, OF BOSTON, MASSACHUSETTS.

SH UTTER-FASTENER.

SPECIFICATION forming part of Letters Patent No. 429,259, dated June 3, 1890.

Application filed March 5, 1890.

To all whom it may concern.-

Be it known that I, DANIEL CHAMBERLAIN, of Boston, in the county of Suffolk and State of Massachusetts, have invented a new and useful Improvement in Blind-Fasteners, which will, in connection with the accompanying drawings, be hereinafter fully described, and specifically defined in the appended claim.

In said drawings, Figure l is a vertical section taken transversely to the plane of the house-wall and through the blind, while the fastener is shown in side elevation in its proper relation to the blind and wall. Fig. 2 is a top plan view of the fastener when in the same position as in Fig. 1.

This invention relates to fasteners by which blinds are held in position when open; and its object is to provide a blind-fastener simple in construction, inexpensive and durable, and which will not only hold the blind when open, but which will hold it parallel with the housewall and at a fixed distance therefrom, for the purposes hereinafter explained.

Referring again to the drawings, A represents the house-wall, which may be of any material or construction.

B is the blind, (shown, as stated, in vertical section,) the lower rail being shown at a and the slats at b.

0 represents the fastener, which is formed with a bar-like part, having three angles or members, of which 0 is formed to be driven into the wall.

d is a vertical portion at right angles to part c, and e is the outer portion at right angles to part (I and parallel with a line prolonged through the axis of part 0.

Upon the outer end of part c is pivoted the well-known button f, which holds the blind open. As heretofore constructed, button f has been mounted upon a straight bar that was driven into the wall, such bar being of a Serial No. 342,688. (No model.)

length to leave but little more space between the button and wall than the thickness of the blind, and hence when the blinds remain open for considerable periods, as often occurs, the effect upon the wall is a permanent discoloration so marked that the spaces so covered by the opened blinds are as positive and distinct as if coated with paint of an entirely different shade from that upon the balance of the wall; but with the fastener provided with the vertical angle (1 to serve as a stop for the blind, and so as to hold it parallel to the wall, allowing a free circulation of air, the quick drying out of moisture aft-er rain falls, and preventing the accumulation of dust and rubbish between the blind and wall, such discoloration will not take place, and the paint upon the blind and wall retains its freshness. Even though the usual straight bar was of sufficient length to allow space between the blind and wall, still the space would not be maintained, as the force of the wind would force the blind close to the wall, where it becomes fastened by the cohesion of interposed debris and the accumulation of dirt and dust in the hinges; hence the importance of the positive stop d to hold the blind at the required distance from the wall.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

As an improvement in blind-fasteners, the bar formed with the angle 0, to be secured in the wall, the angle (Z, depending from part c, to serve as a stop for the blind when opened, and angle 6, extending outward from part d, and having the securing-button f pivoted thereon, substantially as specified.
